Abstract (en)

[origin: EP2413008A1] An electromechanically actuated membrane valve (1a, 1b), particularly for branching ducts of a fluid of sprinkling and/or weed control systems and the like, comprising a hollow valve body (2) which can be associated with an end portion (3) of a branching duct (4) of a fluid or the like and contains inside it a piston (11a, 11b) adapted to interact with a disk-like membrane (10) for blocking the end portion (3) of the branching duct (4). In more detail, the piston (11a, 11b) is movable with respect to the valve body (2) between an open configuration and a closed configuration of the valve (1a, 1b) and the branching duct (4) comprises an internal duct (8) and an external duct (7) which are mutually coaxial. The peculiarity of the invention consists in that it comprises means (18) for reducing the passage section of the internal duct (8), which are associated with the valve body (2) and adapted to interact with the disk-like membrane (10) on the side opposite to the piston (11a, 11b) for the hermetic isolation of the internal duct (7) with respect to the external duct (8) and vice versa.
